>>119778592In Taskmasters defense, I think there is another aspect that isn't touched on. Photographic Reflexes (PR) means he can do anything so long as he seens it, but that doesn't mean that he is actually proficient in it. Every different fighting style uses and trained many different muscles between them, the muscles of a Kickboxer, is different from a Martial Artist, is different from a CQC master.
If I suddenly came into the ability of PR, I would not be physically fit enough to actually do anything I have memorized. As well as, in most, if not all things, it requires a certain mindset and preparation to effectively do, such as; breathing control, muscle control, the right diet of which affects muscle health, density, growth, size, retention, so on, of which PR probably wouldn't be able to gather.
So even if Taskmaster sees something, and can replicate what it looks like or how it works, he's still need to practice proper form and have the right muscles, and so on, or else risk hurting himself.
